My laptop, a Fujitsu Siemens Amilo Pa 1510, is running slower and slower. It takes too long to start up, and even longer to start from sleep mode. When working on it it seems to be "hanging". While typing the letters doesn't show up, like the system can't keep up. (And I'm not THAT fast on the keyboard!

) I don't really know where to look for the reason for this...
I have Vista home basic on this puter. The antivirus program, Norton 360, and has not found anything wrong. I just ran MBAM, and it didn't find any malware. I don't think this has come "over night", but the system has just gotten slower and slower. Anyone like to help me?
